| Zusammenfassung: | The invention provides a cooling liquid function separation type fuel cell cooling system which is characterized in that an electronic thermostat is arranged on a cooling liquid output pipeline of a fuel cell stack, and the electronic thermostat is divided into a small circulation loop and a large circulation loop; when the temperature of the cooling liquid flowing through the electronic thermostat is not higher than the preset temperature lower limit threshold value of the electronic thermostat, the cooling system controller controls the electronic thermostat to enable the cooling liquid to enter the small circulation loop; when the temperature is not lower than the preset temperature upper limit threshold value of the electronic thermostat, the cooling system controller controls the electronic thermostat to enable the cooling liquid to enter the large circulation loop; and when the temperature is between the preset temperature lower limit threshold value and the preset temperature upper limit threshold valu |
